Plague in big greenhouse plant

[fredcann]

Hi Friends, I found this on some flowers this morning.
Is a giant more than 13 feet tall plant in a greenhouse in soil.
Could anyone suggest what to do? As you can see flower are not far from harvest.
Thanks!

Bud rot, cut all plant material off that looks like that and keep trucking

I’ll add the sooner the better as it spreads quickly -

Quickly indeed. Greenhouse grows offer their own challenges especially in cooler climates.

Also the 3rd picture shows a Spider Mite infestation, see the tiny webbing across the top. I think there are signs in the other pictures too, but not as clear. Insect damage is what leads to bud rot in a lot of instances

i am sorry to see that. i think your entire grow is suspect at this point. you are infested with caterpillars, and it is too late to do anything about it.

Next run, treat for cattys, 1/wk at minimum, the entire grow.

Good luck.

Those caterpillar attacks look just like bud rot, because the invaded tissue rots. That webbing might actually be fungus.

When I grew outdoors in the Carolinas, caterpillars were my biggest problem (aside from, oh, I don't know… fear of arrest and prosecution). One year I lost about half the crop. I packed it in after that.

You should find a hole or two, or the actual worm, in the damaged buds.

bt 1x/wk all grow

and there will still be damage, but not total destruction.
